Sayuri Kimachi

Sayuri Kimachi serves as the principal of Seikain Girls' Academy and is the mastermind behind the scheme to abduct Kimito and use him as a so-called 'commoner specimen.' Despite being nearly thirty years old, she persistently insists on identifying herself as a high school girl, a delusion that earns her widespread secondhand embarrassment from those around her. Beneath her harmless and cheerful façade lies a calculating nature, though any pretense of authority crumbles completely in the presence of the formidable head maid, Miyuki Kujo. Ultimately, she functions as a comedic supporting character defined by her flippancy and lack of genuine gravitas.
